Global Configurator (GC) is a windows program that, based on user input, creates a GlobalViewer (GV). GC requests system information such as which devices you have and your current list of IP addresses. With this information, GC creates a GlobalViewer for your specific devices. GC also compiles the event scripts and loads the GlobalViewer and event scripts onto the box. When using GC, the user must specify the port number for each device (for attached devices to be controlled, they must be on that port). In order for multiple IP Link® boxes to appear in the same GlobalViewer, all the boxes must be configured at the same time, using Global Configurator.

GlobalViewer (GV) is a set of Web pages (HTML, XML, JS) and graphics that are loaded into the memory of an IPL box. These pages provide an interface for control of devices attached to the IPL. They communicate with the event scripts running on the box, and the event scripts issue the commands and queries. This communication between the Web pages and the event scripts occurs through predetermined memory locations in the IPL box. GlobalViewer is initially created by Global Configurator (GC); however, it is possible to edit the GlobalViewer HTML, XML, and JavaScript files outside of GC. This edited GV is called “hard-coded” or manually generated GV.

HTTP is an acronym for the HyperText Transfer Protocol (HTTP), a Web protocol based on TCP/IP, that is used to fetch HyperText objects from remote Web pages.

Internet Protocol (IP) is the protocol or standard used to send information from one computer to another on the Internet.

IP address is a unique, 32-bit binary number (12 digit decimal number, xxx.xxx.xxx.xxx) that identifies each sender and each receiver of information connected to a LAN, WAN, or the Internet. IP addresses can be static (see Static IP) or dynamic (see DHCP).

IP Netmask is a 32-bit binary number (12 digit decimal number, xxx.xxx.xxx.xxx) used on subnets (smaller, local networks) to help the router determine which network traffic gets routed internally to local computers and which network traffic goes out on the Internet.

Media Access Control (MAC) Address is a unique hardware number given to devices that connect to the Internet. When your computer or networking device (router, hub, interface, etc.) is connected to the Internet, a table (see ARP) relates the device’s IP address to its corresponding physical (MAC) address on the LAN.

Pass-throughallows control systems to work with the IPL and provides a link between two ports.
